17 celebrity couples you had totally forgotten ever dated

From Julia Roberts and Kiefer Sutherland to Justin Timberlake and Fergie, we bet you didn’t know these guys used to date...

We’ve rounded up the most unexpected former A-list couples from years gone by.

Remember when Justin Timberlake and Britney Spears were the biggest thing on the planet, in all that denim? Of course you do. But did you know that Justin also dated pop princess Fergie, pre-Britney?

Way before he married Mila Kunis, Ashton Kutcher was a red carpet regular with a pre-Mad Men January Jones. Possibly even more unexpected though, is that Ashton allegedly tried to discourage January from acting (yes, there could have been no Betty Draper if he’d had his way).

“[He] was not supportive of my acting,” January told GQ. He was like, ‘I don’t think you’re going to be good at this.”

We’ve also unearthed some pure 90s joy in the form of Julia Roberts and Kiefer Sutherland together on the red carpet – they got engaged after meeting on the set for Flatliners. But Julia is said to have called off their wedding just days before the ‘do, as Kiefer had reportedly been going behind her back. Naughty boy.

And let’s not remember the fact that Tom Cruise and Cher were at one point in time a romantic item, too.

Now see if you can remember the rest of these A-List couples dating…

Julia Roberts & Kiefer Sutherland

A late-Eighties/early-Nineties power couple, Julia Roberts and 24 star Kiefer Sutherland were engaged, too. However, Roberts branded Sutherland as "young and silly" after calling off their engagement in 1991. Kiefer has since said: "There was a huge connection between us but it was more like friends than the passionate relationship that she or I would have wanted. She saw that, I did not.

If you were in any doubt as to whether or not this happened, Cher firmly set the record straight when she was quoted as saying the following actual words: "Tom Cruise is one of my top five former lovers". They had a fling in 1985 - and, in short, everything about this is awesome.
